I'm using one of those keyboards right now. They're great. I got it so that I could actually feel when I pressed a key instead of just hoping that I had. Unfortunately, I don't believe that IBM makes them anymore. I think I may have gotten the last one ever.

By the way, the best way I've found to clean a keyboard is to put it in the dishwasher. Works very well, and only the cheapest keybarods are made of lousy enough plastic to melt in there.

I've also wanted to get a Happy Hacking Keyboard, but they're awfully expensive, even if they do actually put the control key in the right place.
